Description

Technical Field

[0001] This utility model relates to the field of pipe bending device technology, and in particular to a pipe bending device for metal shelf processing. Background Technology

[0002] Metal shelves are commonly used storage equipment in warehousing and commercial settings. They are mainly made of steel and other metals and are assembled through welding. When producing curved supports for metal shelves, a pipe bending device is needed to bend the straight pipes at a certain angle for subsequent assembly.

[0003] In the existing technology, the pipe bending device mainly consists of a fixed plate and a roller that moves around the fixed plate. When in use, the pipe is pressed against the circumference of the fixed plate, and then the roller is moved to bend the pipe against the circumference of the fixed plate, thereby achieving the purpose of bending the pipe.

[0004] The above-mentioned and existing technologies have the following drawbacks: When the tube bending device is used to process the tubes of the metal rack directly in a normal temperature environment, the inner side of the tube will be squeezed and the outer side will be stretched. Therefore, a large stress will be generated in the tube after bending, which will easily cause springback after removal, reducing the practicality of the tube bending device.

[0005] Therefore, a pipe bending device for metal shelf processing is proposed. Utility Model Content

[0006] The purpose of this invention is to solve the problem that when a bending device is used to process the tubing of a metal shelf at room temperature, large stress will be generated inside the bent tubing, which will easily cause springback after removal. Therefore, a bending device for processing metal shelves is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a bending device for metal shelf processing, comprising a support, a fixed plate fixedly mounted on the upper surface of the support, a rotating tube rotatably connected inside the fixed plate, a sliding plate slidably connected to the inner wall of the rotating tube, rollers rotatably connected to the surface of the sliding plate, a first electric push rod fixedly mounted on the upper surface of the rotating tube, the output end of the first electric push rod being fixedly connected to the sliding plate, a motor fixedly mounted on the lower surface of the support, the output end of the motor being fixedly connected to the rotating tube, a fixed plate fixedly mounted on the upper surface of the support, a sliding rod slidably connected inside the fixed plate, an arc-shaped plate fixedly mounted at one end of the sliding rod, and a plurality of electric heating tubes embedded in the arc-shaped plate.

[0008] The effect achieved by the above components is as follows: by setting components such as fixing plates, sliding rods, arc plates and electric heating tubes, the heat of the electric heating tubes can be used to preheat the tubes before bending the support tubes of the metal shelf, thereby softening the tubes to reduce bending stress and thus preventing the tubes from springing back after bending, improving the practicality of the tube bending device.

[0009] Preferably, a spring is fitted around the circumference of the slide rod, and the two ends of the spring are fixedly connected to the fixing plate and the slide rod, respectively.

[0010] The effect achieved by the above components is that the spring can drive the slide rod to slide by its own elastic force, and the slide rod will drive the arc plate to slide, so that the two arc plates are kept in a resisting state, which facilitates the subsequent limiting of the two arc plates.

[0011] Preferably, a guide plate is fixedly mounted on one end of the arc-shaped plate.

[0012] The effect achieved by the above components is that the guide plate can guide the pipe, thereby facilitating the pipe to slide into the inner circumference of the curved plate.

[0013] Preferably, a second electric actuator is fixedly mounted on the lower surface of the support, and a limiting plate is fixedly mounted on the output end of the second electric actuator, the limiting plate being slidably connected to the arc-shaped plate.

[0014] The effect achieved by the above components is as follows: the output end of the second electric actuator extends, the limiting plate moves upward, and when the limiting plate contacts the arc plate, it restricts the position of the two arc plates, which facilitates the subsequent bending of the pipe.

[0015] Preferably, a guide rod slides through the support, and the guide rod is fixedly connected to the arc-shaped plate.

[0016] The effect achieved by the above components is that the movement of the limiting plate will cause the guide rod to slide along the support, and the guide rod will restrict the movement path of the limiting plate.

[0017] Preferably, a rotating ring is rotatably connected inside the fixed disk, a stop bar is fixedly mounted on the upper surface of the rotating ring, and a bolt is threaded inside the rotating ring, the bolt passing through the rotating ring and abutting against the surface of the fixed disk.

[0018] The effect achieved by the above components is that the stop bar can limit the rotation range of the rotating pipe, thereby limiting the bending angle of the pipe and improving the accuracy of the pipe bending device.

[0019] Preferably, a buffer sleeve is fixedly fitted on the circumferential surface of the stop bar, and the buffer sleeve is a rubber sleeve.

[0020] The effect achieved by the above components is that the buffer sleeve can reduce the impact force between the stop bar and the rotating tube.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting components such as a fixing plate, a sliding rod, an arc plate, and an electric heating tube, the heat from the electric heating tube can be used to preheat the tube before bending the support tube of the metal shelf, thereby softening the tube and reducing bending stress, thus preventing the tube from springing back after bending and improving the practicality of the tube bending device.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figures 1-4As shown, this utility model provides a bending device for metal shelf processing, including a support 1, a fixed plate 2 fixedly mounted on the upper surface of the support 1, a rotating tube 3 rotatably connected inside the fixed plate 2, a sliding plate 4 slidably connected to the inner wall of the rotating tube 3, rollers 5 rotatably connected to the surface of the sliding plate 4, a first electric push rod 6 fixedly mounted on the upper surface of the rotating tube 3, the output end of the first electric push rod 6 fixedly connected to the sliding plate 4, a motor 20 fixedly mounted on the lower surface of the support 1, the output end of the motor 20 fixedly connected to the rotating tube 3, a fixed plate 7 fixedly mounted on the upper surface of the support 1, a sliding rod 8 slidably connected inside the fixed plate 7, an arc-shaped plate 9 fixedly mounted at one end of the sliding rod 8, and a plurality of electric heating tubes 10 embedded in the arc-shaped plate 9. By setting the fixed plate 7, sliding rod 8, arc-shaped plate 9 and electric heating tubes 10, the device can achieve the desired bending effect. Before bending the support tubes of the metal shelf, the heating element 10 can preheat the tubes to soften them and reduce bending stress, thus preventing the tubes from springing back after bending and improving the practicality of the bending device. A spring 11 is fitted on the circumference of the slide rod 8. The two ends of the spring 11 are fixedly connected to the fixed plate 7 and the slide rod 8, respectively. The spring 11 can drive the slide rod 8 to slide by its own elasticity. The slide rod 8 will drive the arc plate 9 to slide, so that the two arc plates 9 move closer or further apart, or remain in a resisting state, which facilitates the subsequent limiting of the two arc plates 9. A guide plate 12 is fixedly installed on one end of the arc plate 9. The guide plate 12 can guide the tubes, so that the tubes can slide into the inner circumference of the arc plate 9.

[0031] A second electric actuator 13 is fixedly mounted on the lower surface of the support 1. A limit plate 14 is fixedly mounted on the output end of the second electric actuator 13. The limit plate 14 is slidably connected to the arc plate 9. When the output end of the second electric actuator 13 is extended, the limit plate 14 will move upward. When the limit plate 14 contacts the arc plate 9, it will restrict the position of the two arc plates 9, which facilitates the subsequent bending of the pipe. A guide rod 15 slides through the support 1. The guide rod 15 is fixedly connected to the arc plate 9. When the limit plate 14 moves, it will drive the guide rod 15 to slide along the inside of the support 1. 15 achieves the function of limiting the movement path of the limiting plate 14. A rotating ring 16 is rotatably connected inside the fixed plate 2. A stop bar 17 is fixedly mounted on the upper surface of the rotating ring 16. A bolt 18 is threaded inside the rotating ring 16. The bolt 18 passes through the rotating ring 16 and abuts against the surface of the fixed plate 2. The stop bar 17 can limit the rotation range of the rotating pipe 3, thereby limiting the bending angle of the pipe and improving the accuracy of the pipe bending device. A buffer sleeve 19 is fixedly sleeved on the circumferential surface of the stop bar 17. The buffer sleeve 19 is a rubber sleeve. The buffer sleeve 19 can reduce the collision force between the stop bar 17 and the rotating pipe 3.

[0032] The overall working principle is as follows: When the metal shelf processing tube bending device is working, the tube to be bent is moved so that it slides along the surface of the guide plate 12. The guide plate 12 guides the tube, making it easier for the tube to slide into the inner circumference of the arc plate 9. During this process, the spring 11 can drive the slide rod 8 to slide using its own elastic force. The slide rod 8 will drive the arc plate 9 to slide, so that the two arc plates 9 are kept in abutting state, which facilitates the subsequent limiting of the two arc plates 9. When the tube slides to the appropriate position, the electric heating tube 10 embedded in the arc plate 9 is activated to heat the part of the tube to be bent, softening the tube and reducing the bending time. After preheating, the pipe is moved again to a suitable position on the outer circumference of the fixed plate 2. Then, the output end of the first electric actuator 6 is retracted, and the slide plate 4 slides along the inner wall of the rotating pipe 3, driving the roller 5 to move until the roller 5 abuts against the outer wall of the pipe. Then, the output end of the second electric actuator 13 is extended, and the limiting plate 14 moves upward. When the limiting plate 14 contacts the arc plate 9, it restricts the position of the two arc plates 9, which facilitates the subsequent bending of the pipe. The movement of the limiting plate 14 will drive the guide rod 15 to slide along the inside of the support 1. The guide rod 15 achieves the function of restricting the movement path of the limiting plate 14.

[0033] Then loosen bolt 18, and adjust the position of stop bar 17 by rotating ring 16 according to the bending angle of the pipe. After adjustment, tighten bolt 18 to fix ring 16, and then turn on motor 20. The output end of motor 20 will drive rotating tube 3 to rotate. Slide plate 4 will follow rotating tube 3 to drive roller 5 to rotate. Roller 5 will press the pipe against the circumference of fixed plate 2, causing the pipe to bend and completing the bending action. After rotating tube 3 rotates a certain angle, it abuts against the surface of buffer sleeve 19 on stop bar 17. Buffer sleeve 19 can reduce the collision force between stop bar 17 and rotating tube 3, while stop bar 17 can limit the rotation range of rotating tube 3, thereby limiting the bending angle of the pipe and improving the accuracy of the bending device.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
